MMBZ5239BS-7-F

Overview

The MMBZ5239BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated in an SOT-363 surface mount package. It features planar die construction and provides two independent Zener channels within a single ultra-small footprint. The nominal Zener voltage is 9.1V, with a tolerance range of 8.65V to 9.56V at a test current of 20mA. Maximum power dissipation is rated at 200mW, and the maximum reverse leakage current is specified as 3µA at 7V. The device operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual isolated Zener configuration for compact circuit design
• Planar die construction for reliability
• Lead-free and RoHS compliant manufacturing

Applications

• Voltage reference circuits requiring dual channels
• Automated assembly processes
• General purpose surface mount applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets required environmental standards such as RoHS compliance and moisture sensitivity levels before procurement. Ensure the supplier provides valid traceability data for the date code marking.

Selection Notes

Select this component when dual isolated Zener regulation is needed in a minimal space. The SOT-363 package suits high-density PCB layouts. Verify that the 200mW power dissipation rating and 9.1V breakdown characteristics align with the target circuit requirements.

Part Context

This part belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series offers various Zener voltages in the same SOT-363 package format. The '-7-F' suffix indicates tape and reel packaging with 3000 units per reel.

Replacement Considerations

Direct substitutes include other MMBZ5239BS variants from different manufacturers if pinout and electrical specifications match exactly. Verify package dimensions and thermal resistance values when considering alternatives.
